Lan Cook (Author) Lan joined Usborne after working as a bookseller. She absolutely loves learning about anything and everything. She has lived in China, attempted to create the perfect aquarium biotope, studied Anglo-Saxon, Norse and Celtic at Cambridge University, and can hit an archery target from 100 feet away. Lan has always loved collecting knowledge and as many weird facts as possible, so working for Usborne really is a dream job! Tom Mumbray (Author) Tom studied History at university before joining Usborne in 2018. Since then he's worked on books about Planet Earth, technology, maths and inventions (and learned lots of amazing facts about everything from paleoburrows to fireworks along the way).
